About the role

Highlight 5.5 Working Days Medical Benefits Shuttle bus provided Position Objective and Summary The WWTP Process Engineer is responsible for the operation, monitoring, optimization, and continuous improvement of industrial and hazardous wastewater treatment processes at the wastewater treatment plant (WWTP). This role provides technical judgment, process troubleshooting, and engineering support to ensure stable compliance with discharge standards, operational efficiency, and EHS requirements. Main tasks /Activities / Responsibilities 1. Process Operation and Optimization Responsible for daily operation, monitoring, and optimization of industrial and hazardous wastewater treatment systems. Cover key treatment units, including but not limited to: Physico-chemical treatment: Lamella clarifier, DAF, CAF Advanced oxidation processes (AOP): Micro-electrolysis oxidation, Fenton oxidation, electro-catalytic oxidation, catalytic ozonation, UV photocatalytic oxidation Biological treatment: Anaerobic systems (e.g. UASB, CSTR), aerobic systems (activated sludge, MBR) Tertiary / polishing treatment: MBR, RO Adjust operating parameters based on influent water quality variations (COD, BOD, SS, oil & grease, toxicity, etc.). 2. Technical Evaluation and Process Development Conduct technical evaluation of new incoming wastewater or waste streams and determine suitable treatment routes and pretreatment requirements. Plan, organize, and execute bench-scale tests (e.g. jar tests, pilot trials) to verify treatment feasibility. Provide technical recommendations to support operational decisions and commercial assessments. 3. Troubleshooting and Problem Solving Handle system abnormalities such as effluent non-compliance, biological inhibition, membrane fouling, and process instability. Perform root cause analysis (RCA) and propose corrective and preventive actions (CAPA). 4. Documentation and Technical Management Prepare, update, and maintain SOPs, process operating parameters, and technical reports. Guide technicians and laboratory staff on sampling, testing, and on-site process adjustments. Participate in government inspections, customer audits, and technical discussions. 5.
